Shape Change of LCE-CB sample in scar-tissue-like environment A) Photothermal actuation curves of LCE-CB sample with 0.4 wt% CB embedded in agar gels with varying agar concentration measured over 2 minutes of continuous 500mW/cm2 IR light irradiation. C) Temperature measurement of LCE-CB sample embedded in agar gels with varying agar concentration measured after 2 minutes of continuous 500mW/cm2 IR light irradiation. Temperatures are measured at the sample surface (TS) and agar surrounding the sling (TA) (2mm vicinity) after 2 minutes of continuous IR light irradiation. D) Images showing contraction along the width and elongation along the length and temperature of the sample and surrounding agar of an LCE-CB sling with 0.4 wt% CB embedded in 1% agar gel. LCE-CB sample at 0 seconds with IR off (left), sample actuation and temperature measured after irradiation with 500 mW/cm2 IR light for 60 seconds (middle), and sample actuation and temperature measured after irradiation with 500 mW/cm2 IR light for 120 seconds. Three samples are evaluated from three different batches in each agar gel (n=9 for each composition). Error bars represent standard deviation. Scale bar: 1mm.
